I am currently using this to serve up my homes internet using PFSense. It easily handles my homes 1GBps internet service. The latest speediest.net I ran got me 970Mbps Down. It also has been completely stable; uptime is around 90 days right now. It also sips power; I had an hourlong power outage the other day and it was efficient enough to keep running on its UPS until the service was restored.

I was able to grab the N5105 barebones version and then ordered a 2x8gb ddr kit and a 256gb nvme (overkill for both).

Received the first unit, had some issues installing an OS on the system. Crashed during boot, crashed during install, never would complete install. During troubleshooting it was found that the RAM was bad. Reseating the RAM didnt help, unit was received DOA.

The PC itself is great. Using mine with pfsense. I did have a ram stick die shortly after getting things running, but the seller actually responded pretty quick and resolved the issue.

I purchased 16 GB this RAM: https://www.amazon.com/gp/product/B0B8NTKC19/ref=ppx_yo_dt_b_asin_title_o01_s01?ie=UTF8&th=1

I have been running a QOTOM-Q355G4 24/7x365 as my OPNsense router since 2017 and it has never gone down. Thats going to be a hard act to follow, but its getting old so I used 2.5Gbe as an excuse to upgrade to this box.

Update: The seller made everything right. They sent me a pre-paid label to ship the DOA unit back and shipped me a new unit. The new unit worked perfectly.

Setting this up as a router with OPNsense and AT&T Fiber internet. I did not know this until after but there is a compatibility issue with the Intel I225-V nic and one of the gateways that AT&T Fiber uses for GPON/ONT setups (Pace 5268AC). It will not negotiate at all and is essentially dead. This can be worked around by placing a switch between the gateway and this device.

Used this to make a router. Works great - does Quality of Service at better then GB speeds.

I purchased a few other units like this one and of all the ones I tried, this one is the best.
